crew

I'm a little stuck... Click here to teach me more about this clue!

'hands' is the definition.
(I've seen this before)

I can't explain the remainder of the clue.

(Other definitions for crew that I've seen before include "Was exultant" , "Made early call" , "Ship or aircraft staff" , "eight, say" , "Train team" .)

I've seen this clue in the Evening Standard.
